Last week, Lucky Charms announced they were killing off one of their marshmallows, the yellow and orange hourglass. It had only been part of the cereal since 2008, so no one got all Internet angry over its death. But people are certainly getting Internet happy over its replacement. General Mills just announced the new, permanent marshmallow they're adding in its place . . . the MAGICAL UNICORN. The marshmallow is a white unicorn head, with blue and purple swirls on the mane and the horn. Boxes of Lucky Charms with the new unicorn marshmallows are already starting to ship out, and they should be everywhere by next month. (PR Newswire)
